Claim: 'greenhouse gases could extend California drought for centuries'
From the UCLA Newsroom: Pacific Ocean’s response to greenhouse gases could extend California drought for centuries Warming forces have caused millennia of dryness in California’s prehistory, and greenhouses gases could…
NASA predicts a 'return to normal' in ENSO conditions
After Strong El Niño Winter, NASA Model Sees Return to Normal Not too hot, not too cold – instead, water temperatures in the equatorial Pacific Ocean should be just around…

NOAA Cancels La Niña Watch While La Niña Conditions Exist
Guest Post by Bob Tisdale La Niña conditions are typically defined by NOAA as sea surface temperature anomalies less than or equal to -0.5 deg C for the NINO3.4 region…
New research shows that California's Sierra Nevada snowpack will likely not recover from the current drought until 2019
By Lauren Lipuma, Contributing Writer, EOS The unprecedented drought that has gripped the Southwest United States has severely depleted the Sierra Nevada snowpack, the major source of water for drinking and…
Say Hello to La Niña Conditions
